Question/feature: access DI through ADR?

[cxj]

It would be convenient in a few cases if I could call Aura DI methods through the ADR object, like I can with the route methods. I'm imagining something like this:

$adr->di->values[$key] = $val;
// or
$gateway = $adr->di->lazyGet('cxj/db:gateway');

Maybe it already exists? I could not find it, however.
